4.3 Indication of immediate medical attention and special treatment needed, if necessary
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting.

12.2 Persistence and degradability
AEROBIC: 1,4-Butanediol, present at 100 mg/L, reached between 74 and 96 percent of its theoretical biological oxygen demand in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1). Under aerobic conditions, the acetic acid bacteria Acetobacter aceti and Gluconobacter oxidans oxidized 1,4-butanediol to succinic acid(2).
12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated for 1,4-butanediol(SRC), using a log Kow of -0.86(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of 1,4-butanediol is estimated as 8.4(SRC), using a log Kow of -0.84(1)and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,4-butanediol is expected to have very high mobility in soil.
